Up to 1,500 local, national and international media are expected to be at the media filing center at the Polk County convention center in Des Moines for the first-in-the-nation caucus Tuesday night. Media working out of the filing center had access to beverages, food, ice cream, treadmills and tech tools in the Google Hangout, sponsored by Google. Several local vendors set up shop, too, and Google had a technical support team on site. (Photo by Matt Woolbright / for the Register)
